FRESNO, Calif. 
A jury in Central California has convicted a former Marine of killing his 3-month-old son.

The Fresno Bee reports (

) that the jury convicted Robert Quiroz on Monday of second-degree murder and child abuse causing death.

Prosecutors argued that the 25-year-old Quiroz snapped five years ago when he slammed the head of his infant son, Roman, into the armrest of a couch. He was also charged with breaking Roman's left arm and fracturing 10 of his son's ribs.

But Quiroz's attorney said the former Marine never intended to kill his son. Quiroz testified that he was negligent, but that he accidentally inflicted the injury when he lost his balance. He denied breaking his son's arms and ribs.

Quiroz - who was stationed in the Middle East - lost his wife to an aneurysm and was left to care for the infant and his 14-month-old daughter.
